        Web Inspector: innerFirstChild has a side effect which should be called explicitly.

        If a node is a frame's owner then innerFirstChild method
        subscribes DOMAgent instance to the frame's doc's events.
        I think this should be done explicitly when we meet with
        the node for the first time. As I understand it happens
        in buildArrayForContainerChildren method.
